Product Information

 

 

Duplex stainless steel has the following performance characteristics:
(1) molybdenum-containing duplex stainless steel has good resistance to chloride stress corrosion at low stress. General 18-8 type austenitic stainless steel in the 60 ° C above the neutral chloride solution prone to stress corrosion fracture, in the trace of chloride and hydrogen sulfide industrial medium with such stainless steel heat exchangers, evaporators and other equipment There is a tendency to produce stress corrosion fracture, and duplex stainless steel has a good resistance.
(2) molybdenum-containing duplex stainless steel has good resistance to pitting corrosion resistance. The critical pitting potential of duplex stainless steels is similar to that of austenitic stainless steels when they have the same pitting resistance equivalent (PRE = Cr% + 3.3Mo% + 16N%). Two-phase stainless steel and austenitic stainless steel wear resistance and AISI 316L considerable. The corrosion resistance and crevice corrosion resistance of 25% Cr, especially nitrogen-containing high chromium duplex stainless steels, exceeds AISI316L.
(3) has good corrosion resistance and wear corrosion resistance. In some corrosive medium conditions, suitable for the production of pumps, valves and other power equipment.
(4) comprehensive mechanical performance is good. Has a higher strength and fatigue strength, yield strength is 18-8 type austenitic stainless steel 2 times. Solid solution of the elongation of 25%, toughness AK (V-slot) in more than 100J.
(5) good solderability, hot cracking tendencies are small, the general welding without preheating, welding without heat treatment, with 18-8 type austenitic stainless steel or carbon steel and other dissimilar welding.
(6) with low chromium (18% Cr) duplex stainless steel hot working temperature range than 18-8 type austenitic stainless steel wide, small resistance, can not go through forging, direct rolling billet production plate. Double-phase stainless steel with high chromium (25% Cr) is slightly more difficult to process than austenitic stainless steel and can produce products such as plates, tubes and wires.
(7) cold processing than 18-8 austenitic stainless steel processing hardening effect, in the tube, board to bear the initial deformation, the need to exert greater stress to deformation.
(8) compared with the austenitic stainless steel, thermal conductivity, linear expansion coefficient is small, suitable for equipment lining and production of composite panels. Also suitable for the production of heat exchanger die, heat transfer efficiency than the austenitic stainless steel.
(9) There are still a variety of brittle tendencies of high chromium ferrite stainless steel and should not be used at temperatures above 300 ° C. The lower the chromium content in the duplex stainless steel, the less harmful the brittle phase.
